1. M.A.S.H. (TV not movie) Watched every single one of these at least once...including the pilot. I've even got every single episode on either DVD or Video.
2. Hill Street Blues. Let's be real careful out there. Absolutely brilliant characters. Frank Furillo and his fruitcake wife Fay. Joyce Davenport - the hottest DA out there! Belker and Renko. Great programme.
3. Life on Mars. Another series with superb characters. Gene Hunt and Ray Carling. Didn't rate Ashes to Ashes as much.
4. Absolutely anything that is narrated/fronted by David Attenborough. Originals/reruns, don't care. Got the full boxed set which is still, after probably a good dozen years or so, doing the rounds with the grandkids...and the kids across the road. Timeless.
5. The Two Ronnies. Funniest thing on TV.
There's loads of honourable mentions...Red Dwarf, Dr Who, Monty Python, loved Tomorrow's World - good laugh to go back through them now just to see how wrong they got it with some things.
